Bests & Worsts Reviews from Amazon

I was thrilled to get this but figured I'd test it a few times to see if it works. My first test. I connected to a Bluetooth music receiver , I let the music play and then put my phone into this bag. The music stopped. 2nd test.. I had wifi turned off and data turned on, I put phone into bag and sent a text to my phone via pc. No sounds of receiving a text. I took phone out of bag and a few seconds later the text arrived! So far so good. I then turned off data and turned on wifi and repeated the previous test. Worked great! I was going to leave it at that but decided to download the MD Faraday bag testing app. This is kind of contradicting as it makes you let the app have permission to access all aspects of phone including photos. I downloaded it anyway, Started the test, put phone in bag (yes, closed it properly). Waited about 20 seconds and took out the bag. At first this test failed and I jumped the gun and gave a 1 star but I read instructions again. It seems you must take device out of bag and wait about 30 seconds before stopping the test. Each time I did this, it passed with flying colors so it's 5 stars. UPDATE... It's been about 6 weeks of using this bag. It mostly works BUT today I tested it 3 times in a heavy populated area while driving and it failed 3 times. When I got to a less populated area it passed. Shouldn't this either work or not work. Maybe I'm mistaken but I would think it should work when stationary or while driving. Bumping it down a star.
